PORTABLE ELECTRIC WINCH.

SPECIFICATION forming part of Letters Patent No. 773,867, dated November1, 1904.

Application filed March 14, 1904.

To all whom it may concern:

Be it known that I, JAMES HEYwooD, a citi- Zen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a certain new and useful Portable Electric inch, of whichthe following is a specification.

My invention relates to winches, and has for its object the productionof a machine of this class which can be safely and advantageously usedfor the drawing in of electric cable into conduits and the like.

My invention consists, essentially, of a strong frame mounted on wheelsand so designed as to be anchored at one end and to safely take a heavystrain at the other. Upon this frame I place a drum, preferablyvertical, an electric motor bolted to the frame and geared to the drum,together with a switch or controller of suitable design mounted inconvenient position to be quickly and easily manipulated from behind themachine. To this outfit I add a rod or rods carrying conducting-wiresand clamps to be lifted up and hooked over the trolley-wires when thework is along the line of a traction-road. I do not limit myself to thismeans of obtaining current, but find it convenient. The motor I employis a series-wound machine which increases its torque by increase ofcurrent due to falling off of counter electromotive force as the loadincreases and speed diminishes. The torque is thus proportional to theload.

The machine is very compact, is readily moved about and transported, andconsumes no power when not in use. Moreover, it requires no skilledattendant, and by having the different parts properly incased it can beused in all weathers and under the most trying conditions.

My invention is illustrated in the accompanying drawings, wherein Figurel is a side view of the device, the near wheels being removed. Fig. 2 isa'rear view thereof, and Fig. 3 is a sectional view of the castbed-plate upon which the windingdrum is mounted.

Referring to the drawings, A A are side members constructed ofchannel-iron and secured together by the transverse members B Serial No.198,077. (No model.)

and C, these being bolted to the channels, as shown at b and 0,respectively. In addition the member B, which is in effect a bolster orbed-plate for the winding-drum, arches across the flange a and is boltedthereto at Z). The front of the bolster B drops to the upper flange a ofa front transverse member A, and secured thereto by the bolt h is a hookH, used for draft purposes or the like. To the transverse web A issecured the bearingplate t for the front or guiding truck T. This hasthe lower plate 25, the tongue t the wheels t and the axle t.

The casting B, which is separately shown in section in Fig. 3,constitutes an important feature of my design. It has a raised portionZ2 constituting a bed-plate for the bolster N, to which is secured bybolts n the electric motor M. It also has a raised portion 6 with itsupper face trued off to afford a bearing-face for the drum D. A hollowboss I) is produced in the casing, strengthened by the web 6 connectingit to the front wall 6 and bored out at .6 for the reception of thevertical shaft S of the drum. The drop member 6 of the casting extendsthe full width of the machine and receives the bolts 5 passing throughthe webs of the channelironsA and A. In addition it carries the bearing6 for the shaft S, the shaft being inserted from beneath, and thisserving as a foot-step to carry the weight of the gears, &c., if drum Dis removed.

Mounted also on the bolster N at opposite ends are the journal-blocks nand n upon which are supported the boxes m and m carrying the bearingsfor the motor-shaft m. Upon the rear end of this shaft is a pinion mmeshing with a toothed wheel 3, carried upon the rear end of thelongitudinal shaft S. This shaft is journaled at its forward end in abearing 6 supported in a drop extension 6 of the casting B, and at itsrearward end the shaft is journaled in a similar bearing in the castingO. This casting has an upper face 0 in the same plane with the face" If,serving therewith to support the bolster N. To the rear of the casting Glies the gearwheel 8, and this is inclosed, together with the pinion, bya suitable casting m At the IOO - of supply.

forward end of the shaft S is a bevel-pinion s, and meshing with this isa horizontal bevelgear 6 secured to the lower end of the vertical shaftS. The upper end of this shaft is threaded, and below that it issquared. The drum D has cast-iron heads (Z and (Z, each with a squaredhole, the body of the drum being confined between these heads and madeup, preferably, of sections each having a squared hole to fit the shaft.In assembling, the shaft S, with the beveled gear secured on it, isinserted through the casting from below, the collar or step-bearing 6 isthen put in position and bolted fast, and finally the parts of the drumD are slipped down over the shaft and secured by the nut (Z At the rearend of the machine I provide two oblique angle-plates Q, bolted to theside channels at Q and carrying the clevises q, secured by bolts in theusual manner and intended to be used for anchoring the machine duringoperation. These angleplates are raised above the side plate so as tobring the clevises q approximately in the same place as the base of thedrum. Upon each side channel-iron a plate P is bolted at 2, beingperforated for the passage of the axle p.

The operation of my invention is as follows: The machine having beenmoved in proximity to the drawing-out manhole, the dragrope is passed upover the usual sheaves and then horizontally to the drum D, around whichit is given a few turns, and the end retained by the workman, who standsready to take up slack. A suitable cable is passed around a post orother secure anchorage and the ends are attached to the clevises Bymanipulating the controller X (see Fig. 2) the attendant then admitscurrent to the motor, connection having previously been made, as alreadydescribed, to the trolley-wire or other source The movement'of thearmature of motor M is imparted, through its shaft m and the pinion m,to the gear-wheel s and the shaft S. From this it is communicated bybevel-gears s and s to the shaft S and thence to the drum D. As the drumturns it draws in the cable, and after a little practice the attendantwho keeps the rope taut can tell almost as well by feeling the conditionof the cable as by the signals from the other manhole. It follows fromthis also that the strain on the rope is easily regulated by permittingmore or less slip around the drum.

As shown in Fig. 1, the working parts of my machine are usually housedin a casing indicated by dotted lines. The gears are all incased, andeven the journal-boxes can be inclosed to exclude dust and moisture.

I am aware that many changes may be made in matters of detail withoutdeparting from the spirit of my invention, and all such changes Iconsider as fairly included within the scope of my claims.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is

1. A portable electric Winch comprising the following instrumentalities:a truck having side frames of channel-beams and cross members of archedform strengthened by flanges in the direction of thrusts, an electricmotor and winding-drum mounted on said truck, the forward arched memberof which is provided with a vertical bearing and a winding-shaft in saidbearing, a longitudinal driving-shaft and gears connecting the drum andmotor, bearings for said shaft formed in drop members formed on theunder side of the arched cross members of the truck, substantially asdescribed.

In a portable winch, a bed-plate composed of an arched portion, a hollowboss formed therein for the vertical shaft, a second hollow boss for thehorizontal shaft, a brace or flange for the foot-step bearing, andconnectingwebs, whereby the alinement and enmeshing of shafts and gearsis rendered certain under all conditions, substantially as described.

In witness whereof 1 have hereunto set my hand in the presence of twowitnesses.
